If there is any update at all.

Just wondering as I have SIM Free iPhone 4.

Updates for all iPhones (SIM Free or otherwise) come from Apple through iTunes.

Apple doesn't allow carriers to brand their phones in any way, so there is no need to delay firmware updates.
 
All iPhones, regardless of carrier or whether they're sim-free get their updates direct from Apple via iTunes
